Oh, alright! No extra string issues?

RE: Loose Heater Block after changing nozzles

Bought the standard version of the dragon hotend, will not print super fast with a big nozzle. 

I will try this when I get home from school today, 

1 .Remove the hotend

2.Remove the cables that is connected to the hotend

3. Re-install it following E3D guide.

4. Re-assemble everything again.The guides i have been following:Removing the hotend

Help with re-assemble V6 Hotend

I will confirm if this works later, thanks!

RE: Loose Heater Block after changing nozzles

Hope you can make it work! I'm wondering what you mean when you say "will not print super fast with a big nozzle." What issue are you experiencing? I sell one particular model that would take way too long to print unless I used a 0.8mm nozzle and pushed MVS up to 20 mm3/s. It's fun to watch the extruder indicator circle like crazy!  Now, it's not the Dragon that made it possible, I optimized everything with the stock E3D hotend but the Dragon didn't make it worse. So I'm curious what you're seeing.

Thanks! This has happened to all three of my Prusa MK3S+ factory assembled, so something must have gone wrong when I did it. 

I will not be pushing the dragon hotend over the limits. Print normal speed like an E3D V6 but with more QoL features. 0.8 and 1.0mm nozzle will still work out good. Maybe pushing it later with speed settings but have never successfully pushed time with MVS. 

Really crossing my fingers this will solve it, I don't get how I cant tighten the nozzle more! So annoying. Not the first time I have done this! But the first time this has happened to me, and then with all of my printers! 

RE: Loose Heater Block after changing nozzles

The impact of MVS depends very much on the model. The one I mentioned is basically a large brick, with plenty of long runs where it can get up to speed. On smaller, delicate models with lots of twists and turns, the extruder never gets close to max speed because it has to constantly accelerate and decelerate, so raising MVS has zero impact.

Oh, and I totally misread your point about "will not print super fast". Thought you'd seen an issue trying to do so (insert an embarrassed emoji here) 🙂

No stringing issues.

RE: Loose Heater Block after changing nozzles

All got solved today. 

The problem was that the heaterblock was not tighten correctly or got loose after the nozzle change. 

If this happends, follow this guide: https://help.prusa3d.com/en/guide/how-to-replace-a-heatbreak-heatsink-heaterblock-mk3s-mk3s-mk2-5s-mmu2s_16104/ but you just have to tighten the block with the heaterblock with the hotend again. 

RE: Loose Heater Block after changing nozzles

Glad to hear you're back in business!

RE: Loose Heater Block after changing nozzles

Changed a nozzle now with no problems, all works good also! 
Had todo this on all 3 of my printers, but all good now!
